I just had a new computer built and there seems to be an issue with either it or software. I am not sure where to post this so I figured this forum should be ok ><. My computer will not respond for a minute or two. By not respond I mean just the programs, my keyboard and mouse will continue to work but when I click on something it doesnt open. While it is doing this if I push ctrl alt del it will bring up the blue screen and will have a loading screen instead of the usual "shut off, switch user, etc." After about a minute or 2 everything is ok and the programs I clicked open, but it is getting to be annoying and would like it fixed, especially since it is a brand new computer. I think it may be an issue with videos or my video card.
OK that's weird - it suddenly responds after a while?
Try clearing out dust in the computer - use a can of compressed air on the cpu cooler, gpu cooler, and case fans.
Do you have any programs installed that might be running in the background, hogging resources?
Also, a repair install of Windows might work. Since you said you had the computer built, I'm assuming it wasn't from a bigname brand like Dell, HP, Acer, etc and you have an actual Windows install disc. You will need this for the repair install.
